Tessellation Step 3: Create bottom side

Now we will be creating the bottom of our tessellation.
Create several points, and connect them using the line segment tool.
Make sure you connect your points to the two sides we have created in Step 1 and 2.
Drag and pull the points in the design pattern you want.
Remember, that you will be translating this pattern to the top of the pattern.
